error when installing library
Closed this issue · 6 comments
Hello,
Unfortunately, I get an error when trying to install the luma.led_matrix library. I followed the instructions given here:
https://luma-led-matrix.readthedocs.io/en/latest/install.html
(a) SPI is enabled:
osmc@osmc:~$ lsmod | grep -i spi
spi_bcm2835 7817 0
osmc@osmc:~$ ls -l /dev/spi*
crw-rw---- 1 root osmc 153, 0 Sep 17 15:19 /dev/spidev0.0
crw-rw---- 1 root osmc 153, 1 Sep 17 15:19 /dev/spidev0.1
(b) Dependencies are installed:
$ sudo usermod -a -G spi,gpio pi
$ sudo apt-get install python-dev python-pip libfreetype6-dev libjpeg-dev
$ sudo -i pip install --upgrade pip setuptools
$ sudo apt-get purge python-pip
osmc@osmc:~$ pip --version
pip 9.0.1 from /usr/local/lib/python2.7/dist-packages (python 2.7)
(c) Installing latest version of the library fails:
osmc@osmc:/tmp$ sudo -H pip install --upgrade luma.led_matrix

Any ideas?

Supplement:
RPi Model:
RPi2B
Kernel version:
osmc@osmc:~$ uname -a
Linux osmc 4.9.29-9-osmc #1 SMP PREEMPT Sat Jul 29 01:44:42 UTC 2017 armv7l GNU/Linux
So the actual error is unable to execute 'arm-linux-gnueabihf-gcc': No such file or directory -
basically there is no C compiler installed on your RPi. This sounds like python-dev was not installed correctly (it should ensure that all the compiler dependencies were installed). What is the output of:
$ apt show python-dev
And then can you retry this:
$ sudo apt-get install python-dev libfreetype6-dev libjpeg-dev
$ sudo -H pip install --upgrade luma.led_matrix
Thank you rm-hull for the quick reply. From what I can see, python-dev seems to be installed correctly:
osmc@osmc:~$ apt show python-dev

Sorry for using a german OS. Let me know if something is unclear. After that, when retrying:
$ sudo apt-get install python-dev libfreetype6-dev libjpeg-dev
$ sudo -H pip install --upgrade luma.led_matrix
the error unable to execute 'arm-linux-gnueabihf-gcc': No such file or directory remains.
Any further ideas?
@3zra what about sudo apt-get install build-essential?
@thijstriemstra installing build-essential did the job. Now, the installation of the luma.led_matrix libraries works. Thanks a lot.
Awesome. Now we'll have to fix the documentation across projects I think @rm-hull?
Yep... although I wonder if we should actually expend some effort in unifying the docs into https://github.com/rm-hull/luma.docs
